Hello - I have a Berkely SSHM-2 that I have been using for lawn irrigation for about 10 years. I usually pull it for the winter and store in my garage but I forgot and tonight we will have a hard freeze (18F) so I drained the lines, but then to drain pump I mistakenly unscrewed the Re-circulation Valve instead of the drain plug. In hindsight - everything in the manual says "DO NOT REMOVE" and no other information as to why this is such a no-no to do. I drained the unit but I don't see any information as to how to reassemble/install the valve and or any particularities about it when reassembling. (It looks like it will screw back in). I have totally disassembled and performed an impeller rebuild in August so I am familiar with the pump side. Questions: Anyone know why the documentation says DO NOT REMOVE and is there any concern? Is worst case scenario I will need to pull the pump body to access both sides of the casting to reinstall the valve? Thanks for any help. FF

First time posting. :) House was built in 1967 in Northern Minnesota. It’s currently in the negatives and we have a ton of snow. First sign something wasn’t right. When I use the sink the toilet would bubble. Sometimes sucking the water from the bowl. We went on the roof and cleared the vent. Still having the same issue. I tried plunging the toilet. Then it wouldn’t flush and filled with water. So I bought a 25 foot pistol grip drum auger. Drain seems to be clear. I didn’t hit anything. Went in the basement and found a sopping wet ceiling tile on the floor under the sink. There’s an open exhaust? Type vent with duct tape over it and it pushed water out when we flush or use the sink. Sooo, I tried using the auger in that pipe too. Didn’t find an obstruction. I covered it with a cap and more duct tape for now. Used the sink in the other bathroom and our toilet bubbles. Talked to the septic company he thinks there may be an obstruction even though I didn’t hit anything. Also a plumber with a camera can’t come until late next week.

Goofy open pipe in photo as well. Lift station is 5 feet from basement bathroom. [/i] Do I need to go back on the roof in -30 or could it be something else? Any and all suggestions welcome and appreciated!!! Thank you in advance! Bethany
